title: High volume local infiltration analgesia compared to peripheral nerve block for hip and knee arthroplasty-what is the evidence?
abstract: Since being reported in 2008, high volume local infiltration analgesia (HVLIA) has rapidly gained popularity for patients undergoing hip and knee replacement. We undertook this review to investigate whether there was evidence for equivalence of HVLIA compared to peripheral nerve block techniques with respect to early postoperative analgesia and functional recovery, or for other outcomes such as cost and process efficiency, persistent postsurgical pain and arthroplasty revision rate. We found that despite the popularity of HVLIA, supporting evidence for its use is currently limited. HVLIA certainly provides postoperative analgesia, but it is not clear whether it is equivalent to contemporary peripheral nerve block techniques in terms of either analgesia or early or later functional outcome in the context of a modern, comprehensive enhanced recovery program. Nor is it possible to state whether HVLIA provides benefits in terms of persistent postsurgical pain or cost and process efficiency. Well designed trials directly comparing peripheral nerve block with a standardised HVLIA technique are urgently required.
